Installation

Installation instructions are included with every SNAP'n SAFE square post surface mount breakaway device. It is recommended that this breakaway be installed in concrete surfaces only due to the strength of concrete as compared to asphalt.

Tools required:

½″ socket and ratchet wrench

9/16″ socket and ratchet wrench

Installation instructions:

Remove any burrs or imperfections from the inside of the sign post.

Check hole location of the sign post and anchor post. The bottom hole of the sign post must be ½″ on center (+/- ⅛″) from the end of the sign post.

Determine the location for the surface mount coupler.(Please note that all bolts must be at least 5 inches from all concrete edges.)

Place surface mount coupler on the concrete surface and place the sign post on top of the coupler. Using a level, determine if any washers are needed under the base at the hole location to level out the sign post.

Using the surface mount coupler as a template, mark the location of the three (3) holes to drill. With a ⅜ inch drill bit, drill three (3) holes at least 4½″ deep. It is not necessary to blow the holes out or clean them out.

Clean off concrete surface and align the coupler with the holes. Place any necessary washers under the base as determined in Step 4.

Put one (1) washer on each bolt and install the three (3) bolts. (DO NOT tighten all the way until you are certain that the base is level and all three (3) hole locations are firmly resting on the washers or concrete.)Note: The bolts are carbon steel and are extremely hard. They have a 3,800 pound pull-out strength.

Slide the sign post over the SNAP'n SAFE surface mount coupler and attach with the (2) corner bolts. Use the 2nd and 3rd hole in the sign post for proper alignment. Fasten (1) washer and (1) nut on each corner bolt. Secure hardware evenly by tightening each nut in an alternating pattern.Note: Corner bolts must be installed on the same side of the post. MAX TORQUE = 21 FT LBS.

CORNER BOLTS MUST BE INSTALLED ON SAME SIDE OF THE POSTS, AS SHOWN IN DIAGRAM.
